Information
The main reason for the loss of hydraulic oil filter element is the blockage of pollutant. Pollutant loading process of a hydraulic oil filter element is the process of blocking the through hole of the filter element. When the hydraulic filter element is blocked by contaminated particles, the hole that can pass through the liquid flow is reduced, and the pressure difference must be increased to ensure the flow through the filter material. In the initial stage, because there are many holes in the hydraulic filter element, the pressure difference through the filter element increases slowly, and the blocked hole has little effect on the whole pressure loss. However, when the plug hole reaches a certain value, the plug will become very fast, through the hydraulic oil filter element pressure rise very fast.
The service life of the two filter elements can be compared by the number, size, shape and distribution of the filter material holes of the hydraulic oil filter element. For a filter material of a given thickness and filtration accuracy, the filter paper has fewer holes than the glass fiber filter material, so the filter element of the filter paper material will clog up faster than the filter element of the glass fiber filter material. The filter element of the multilayer glass fiber filter material can hold more pollutants. When the liquid flows through the filter element, the filter layer filters out particles of different sizes. The small holes in the filter material of the rear layer will not be blocked by large particles. Therefore, the glass fiber filter material filter core than the filter paper filter core longer life.
Use of hydraulic oil filter element: in the hydraulic system, it is used to filter out solid particles and colloidal substances in the working medium, effectively controlling the pollution degree of the working medium. The Yinbeier series filter element is a substitute product for the imported filter element. The hydraulic oil filter element can replace the HYDAC filter element.
